ROBERT EDGAR COLE, OF HIGHLAND CREEK, ONTARIO, CANADA.

CUSHION-WHEEL.

To all whom it may concern:

Be it known that I, ROBERT EDGAR COLE, of the village of Highland Creek,in the county of York, in the Province of Ontario, Canada, have inventedcertain new and useful Improvements in Cushion-Vheels, of which thefollowing is the specification.

My invention relates to improvements in vehicle wheels, and the objectof the invention is to provide a simple compact and easily assembledcushion wheel in which there is perfect freedom of movement in theworking parts to reduce the shock or jar to the body of the vehiclewheel, especially when it strikes an obstruction in its path, and alsoto provide a wheel of this class which is not liable to get out oforder, and it consists essentially of the wheel felly, a hub providedwith annular removable flanges forming annular guideways cross boltsextending through the base of the flange in proximity to the hub, radialeye bolts swung thereon provided with nuts at their outer ends, spacingrings through which the bolts loosely pass, thereby holding such boltsequidistant apart, spokes supported on rings and connected to the fellyand compression springs extending between the nuts and the rings betweenthe rings and the cross bolts as hereinafter more particularly describedby the following specification.

Figure 1, is a face elevation of my wheel shown partially in section.Fig. 2, is a central cross sectional view of Fig. 1. Fig. 8 is asectional view showing the wheel partly disassembled.

In the drawings like letters of reference indicate corresponding partsin each figure.

A is the felly or rim of the wheel of any suitable form adapted to thatclass of vehicle to which it is intended.

B is the hub provided with the cylindrical bore B into which the axleextends and is secured by any suitable means. The periphery of the hubis provided with a shoulder B in proximity to the end thereof, a sidedreduced portion B located beneath the shoulder and a further reducedthreaded portion B.

C are annular removable flanges or plates having the central hole Cwhich is formed with a flat sided boundary corresponding to the flatsided reduced portion B of the hub. The flanges C are held in place bythe end nuts C which are threaded onto the reduced portion B of the hub.By this Specification of Letters Patent.

construction it will be seen that the flanges C are rigidly secured tothe hub B and rotate in unison therewith.

'D are cross bolts which extend through the flanges C near the inneredges thereof and are secured therein by suitable nuts l).

D are eye bolts swung on a cross bolt D at a suitable distance from eachend thereof. The eye bolts D are held in longitudinal position upon thecross bolts D by intermediate spacing plate D having holes 1) throughwhich the eye bolts extend. It will be noticed that the eye bolts D aredesigned to extend normally radially from the hub.

E are angle iron rings provided with slotted holes E through which theeye bolts are designed to extend.

F are compression springs encircling the eye bolts D and extendingbetween the angle iron ring E and the spacing plate D By this means itwill be seen that the ring E is supported normally concentric with thecenter of the hub B.

G are spokes which are formed with an inner broad U-shaped portion G,designed to extend and fit between the rings E and to extend radiallytherefrom. The radially extending members of the spokes are bentinwardly toward the center of the wheel and preferably slightly spreadcircumferentially apart, toward their outer ends as indicated by Fig. 1of the drawing. The ends of the spoke members are secured to the rim ofthe wheel by any suitable means.

G and G are rivets designed to secure the U-shaped portion of the spoketo the angle iron rings E.

It will be understood that the eye bolts D extend loosely through thehorizontal portion of the spoke member.

H are nuts threaded onto the outer extremity of the eye bolts D H arecompression springs encircling the eye bolts and extending between thenuts H and the horizontal portion of the spoke member therebyresiliently securing such spoke member to the angle iron rings E.

I are cross bolts extending through the outer portion of the flanges G.The cross bolts I are provided with spacing sleeves I designed to holdthe outer portion of the flanges rigidly in position.

It will be seen from this description that when my wheel comes incontact with an obstruction it not only has movement on the verticalplane tending to throw the wheel into an eccentric position withrelation to the hub but also a slight circumferential movement due tothe connection of the spokes to the hub by means of the angle iron ringsE, the eye bolt D the cross bolt D. By this arrangement it will be seenthat my wheel is cushioned to a maximum amount against shock due tocoming into contact with an obstruction.

It will also be seen that in case of repair, being necessary through thebreaking of the spring, or other cause my Wheel is very simplydisassembled by removing the bolts D and nuts D and the nuts H so as toenable the bolt D to be withdrawn through the slotted hole E in atangential direction to the periphery of the hub, thereby enabling a newspring to be inserted upon the eye bolt when necessary.

It will also be seen by this description that my wheel is very simpleand compact in construction and that there is perfect freedom ofmovement between all the parts which will obviate any danger of theirbinding.

hat I claim as my invention is:

In avehicle wheel, the combination with a hub having reduced outer endsformed with flat sided portions and a further reduced threaded portion,of annular plates designed to fit on the flat sided reduced portions ofthe hub, nuts designed to be threaded onto the threaded portion of thehub against the central portion of the annular plates, cross boltsconnecting the annular plates in proximity to the hub, intermediatecross bolts connecting the plates in proximity to the outer edgethereof, spacing rings held between the plates and having peripheralslots in the peripheral portion thereof, eye bolts swung upon the crossbolts located in proximity to the hub and extending intermediately oftheir length through the slots in the spacing rings, nuts threaded on tothe outer ends of the bolts, spiral springs inserted between the eyes ofeye bolts and the spacing rings, and between the spacing rings and theaforesaid nuts, and spokes suitably secured to such spacing rings andextending outwardly in an inclined direction to the rim of the wheel.
